-## Unreleased
-
- **refactor: Valve's package mirror in one module (`lib/valve-mirror.sh`: newest repo, package database fields, checksummed download); the SteamOS extras, CEC driver, BIOS lookup and os-release version used four copies**
- **refactor: the rules between menu items are three tables (`REQUIRES`, `FOLLOWS`, `EXCLUDES` in `lib/menu.sh`) used by the menu's toggles and, as `normalize_wanted`, by the app's selection (it had its own copy of the rules). The app now also ticks the Steamify shortcut for "Add as non-Steam game" and unticks the game entry with it, like the menu**
- **refactor: the entry point picks its mode once (`MODE`) and `--defaults` and `--boot` are functions with one failure report, instead of four booleans and two copies of the apply-and-report code; `NO_COLOR` gives plain output**
- **refactor: `is_wanted` and `is_current` instead of repeated `[[ "${WANTED[x]}" == 1 ]]` checks in the menu, the app's backend and the entry point**
- **refactor: the start of every item's JSON (id, label, hint, kind, parent) is built in one place (`json_item_head`) for the app and the installer page, and `json_bool` replaces the `&& echo true || echo false` copies**
- **ci: a Lint workflow runs shellcheck on the modules and helper scripts, ruff on the app and `patches/*.py` (`ruff.toml`) and qmllint on the QML (not blocking until it has run once on the runner); `make lint` runs the same locally**
- **refactor: `best_effort` for the steps whose failure doesn't matter (stopping or disabling units, removing packages, `modprobe -r`, ...): same behaviour, but their errors go to `~/.local/state/steamify/log/steamify.log` instead of `/dev/null`; temp dirs are registered with `make_tmpdir` and removed by the one exit handler (also when a run is interrupted), which replaces the menu's own `EXIT` trap**
- **refactor: the retired kernel pin moved out of `lib/steam-machine.sh` into `lib/kernel-pin.sh`**
- **refactor: the shortcut's two start scripts are files in `patches/` (`steamify-start.sh`, `steamify-app-start.sh`) instead of heredocs in `launcher_enable`, and the 83-line LED driver install is split into steps (`led_write_dkms_override`, `led_install_package`, `led_build_all_kernels`, `led_load_module`); what gets installed is byte-identical**
- **fix: the daily update check no longer crashes on a release tag that isn't a plain version number (`TypeError` comparing it, found by the new unit tests); it is simply never offered**
- **refactor: `theme_enable` and `create_desktop_shortcut` split into steps; the Return to Gaming Mode shortcut is written with its mode already set (`install_executable`), like the other shortcuts, instead of chmod afterwards**
- **test: the menu rules, the plan and the app's and installer's JSON are checked against a golden file (`tests/menu-test.sh` in steamify-cachyos-dev); `make check`, `.editorconfig`, `.shellcheckrc`**

-
- `2e51d1d`, `3494924`, `fbdad5a`, `079e725`, `188799e` **feat: "Start Steam silently" sub-option: under the SteamOS conversion (`silent`, opt-in now: it was always on before; an existing one is moved from its systemd unit to the autostart entry by the "update") and under Gaming on NVIDIA (`nvsilent`, opt-in, not together with Big Picture); the SteamOS one is called "Start Steam silently in desktop mode" and is always shown, also on a Steam Machine; it is Steam's own autostart entry (`~/.config/autostart/steam.desktop`), so Steam's setting "Run Steam when my computer starts" follows it**
- `2f7b53f` **fix: the Steam Machine's serial number step no longer fails inside the ISO's installer (`/sys` is read-only in its chroot; the tmpfiles.d file applies at the next boot anyway), which made `machine` report an error and the install log end with `exit: 1`**
- `45a23af`, `bd8f387` **feat: `STEAMIFY_NO_DOWNLOAD` (the ISO's `steamify.nodownload` kernel parameter): the installed system's first login runs the Steamify bundle of the ISO instead of downloading the newest release (to test an unreleased Steamify)**
- `f3810a9` **fix: the SteamOS theme no longer leaves a blank Discover pin in the taskbar (Plasma's default taskbar pins Discover, which CachyOS doesn't install); the taskbar gets CachyOS's own pins (System Settings, files, browser), also on the ISO's first login**
- `7869b47` **feat: "Steam Deck/Machine icons" (`glyphs`) is a sub-option of the SteamOS conversion, like "Start Steam silently in desktop mode": it only changes gaming mode**
- `4d387b2` **chore: the Steamify unit tests (`controllers-test.sh`, `nvidia-test.sh`) and the NVIDIA hardware test live in steamify-cachyos-dev (`tests/`) now; `tests/` is removed here**
-
-## 2.10.0 - 2026-10-01
-
- `d6db4f6` **feat: "Gaming on NVIDIA" (nvidia) replaces the SteamOS conversion on PCs with an NVIDIA GPU, where gamescope's gaming mode shows a corrupted picture (NVIDIA bug 5240452): Steam is installed when missing and starts at login on the Plasma desktop; the sub-option "Steam starts in Big Picture" (bigpicture) starts it in Big Picture, unticked in its normal window, on an empty Plasma session so windows of the last session don't cover it. On a supported card (RTX 20 series or newer) it also sets the NVIDIA kernel parameters and early modules. The conversion and its options are hidden there unless already on**
- `d1373e2` **feat: single user mode also works on NVIDIA PCs, without the SteamOS conversion**
- `5811f5c` **fix: "Add as non-Steam game" isn't offered on NVIDIA PCs (shown when already on, so it can be turned off)**
- `83248a8` **feat: Extended controller support (extended_controller_support, off by default): the Xbox wireless dongle (xone) and Xbox controllers over Bluetooth with rumble and battery level (xpadneo), built for every installed kernel; off removes only what Steamify installed**
- `01a77b7` **feat: a new opt-in option (unticked by default) shows the "new" badge in the menu and the app**

- `90bc5e4` **fix: HDMI-CEC: Valve's CEC driver is downloaded once and kept in /var/cache/steamify (GitHub rate-limits repeated downloads with HTTP 429, which left CEC off); turning CEC on again needs no network**

- `27a4070` **fix: Steam's OS Variant shows Steamify's version (VARIANT_ID=steamify-2.9.0; Steam shows VARIANT_ID, not VARIANT)**
- `44bfe07` **fix: No VERSION_ID in os-release: About this System said "CachyOS Linux 2.9.0"; the version is in VARIANT ("Steamify 2.9.0")**
- `435f69c` **feat: Steam's System settings: the OS name stays CachyOS (no renaming, also not in About this System), Steamify <version> as the variant, the SteamOS release it follows as the codename (steamos-3.9)**
- `ce71b34` **feat: Steam's System settings and About this System like on SteamOS: OS name "CachyOS with Steamify" (lsb-release, kept through CachyOS updates by a pacman hook), Steamify as OS variant and version (os-release VARIANT/VERSION_ID; NAME/PRETTY_NAME stay CachyOS's for limine, TARGET_OS_NAME pinned), "CachyOS Linux with Steamify" in About this System; on a Steam Machine the serial number and Steam's Wi-Fi backend setting (existing installs get it as an update)**
